I’m surprised how little I burned this winter, just two face cords and 235 gallons of LP. Not bad considering it gets quite cold up here and we had that cold spell in February where we were below -20 quite a few times and down to -35 one night, that’s when I used a lot of propane since I was sick in bed for some time there and I couldn’t burn my wood... ( ͡° ʖ̯ ͡°). I imagine the new windows and polystyrene that was added to the walls under the new siding last year helped.
